Seasonal Affective Disorder: How I’m Supporting Myself This Winter
Every year, right after Thanksgiving, I feel it creeping in.
That heaviness in the morning.
The dip in motivation.
The urge to skip the gym and order takeout instead of cooking.
And the rising stress that follows behind those feelings.
Seasonal Affective Disorder (SAD)—a very fitting acronym for a condition where one of the hallmark symptoms is simply… feeling sad.
A certain level of slowing down at this time of year is natural. We’re cyclical beings living in a cyclical world. Just like the plants and animals around us, our bodies shift with shorter days and colder temperatures. Sometimes it’s okay to lean into that slower pace rather than resist it.
But when the seasonal shift begins to affect your daily functioning, your emotional wellbeing, or your sense of self—that’s when it becomes more than an adjustment. That’s when it becomes something to support.
Why SAD Happens
SAD is not “just in your head.” It’s deeply physiological. The decrease in daylight affects multiple biological pathways:
Serotonin
Sunlight enters the eyes and stimulates serotonin production—a neurotransmitter essential for mood, motivation, and emotional stability.
Less sunlight = lower serotonin, which is strongly linked to low mood.
Melatonin
Melatonin is produced in response to darkness. Light in the morning naturally stops melatonin production and increases cortisol, which wakes you up.
Shorter days disrupt this cycle, leading to:
· morning grogginess
· oversleeping or insomnia
· difficulty regulating your sleep–wake rhythm
Vitamin D
UV exposure triggers vitamin D synthesis in the skin. Vitamin D plays a crucial role in serotonin regulation and immune function.
Low sunlight → low vitamin D → altered serotonin activity.
Circadian Rhythm Disruption
Reduced daylight alters the suprachiasmatic nucleus (your internal clock), causing:
· lower daytime energy
· flattened cortisol curve
· increased inflammation
· changes in metabolic function
This combination affects mood, cognition, appetite, and motivation—making winter feel heavier than it should.
Common Symptoms of SAD
Emotional Symptoms
· Persistent low mood or sadness
· Anxiety or a sense of emptiness
· Irritability or frustration
· Feeling hopeless, guilty, or disconnected
· Loss of interest in hobbies or social events
· Withdrawing from loved ones
Physical Symptoms
· Low energy / fatigue
· Carb cravings or increased appetite
· Weight changes
· Sleeping too much or struggling to sleep
· Sluggishness or feeling “slowed down”
How I’m Supporting Myself This Winter
Here’s what I’ll be leaning into to stay grounded, nourished, and connected:
Light Therapy
Light therapy mimics natural sunlight and helps reset circadian rhythms, increasing serotonin and encouraging proper production of melatonin.
· 30 minutes each morning
· A 10,000-lux light box (make sure it’s non UV emitting)
Warming Foods + Spices
Warming foods support digestion and circulation, helping counteract cold-induced stagnation.
· Warming spices: Ginger, turmeric, cumin, cinnamon, black pepper
· Root vegetables, soups, stews, grains
· Fewer cold/raw foods during deep winter
Evening Routine for Nervous System Calm
A grounding nighttime routine supports melatonin production and better sleep.
· Warm tea
· Shower or bath
· No screens after 8 p.m. (realistically… sometimes there’s Netflix)
· Consistent bedtime
Movement That Warms + Energizes
Movement increases endorphins and improves serotonin metabolism.
· Yoga or Pilates in a warm studio
· Weight training—always
· Daily walks, 10,000 steps (I know it’s so overstated.. but it is for a reason!) supports mood + circulation
Actual Sunlight + Fresh Air
We are nature. Getting outside is non-negotiable for circadian balance.
· Even 10 minutes helps
· Dress for the weather – there is no such thing as bad weather, just bad clothes for the weather!
Adaptogens for Stress + Mood
To support cortisol regulation, energy and nervous system balance, some of my favourites:
· Ashwagandha
· Reishi
· Cordyceps
Gut Health Support
Your gut produces ~90% of your serotonin—so supporting gut health is essential for mood. General gut support:
· Probiotics
· Prebiotic fibres
· Mucilaginous foods: chia, flax, slippery elm
For more individulaized gut support, it may be worth looking to GI Map testing to get a better idea of what your gut health is looking like. Click HERE for more info
Staying Connected
Isolation worsens SAD.
· Quality time with loved ones
· Reaching out instead of withdrawing
Mineral Balancing
Minerals profoundly affect brain function, acting as cofactors for energy, neurotransmitter synthesis, and cell structure
· Deficiencies (like iron, zinc, magnesium, iodine) linked to fatigue, poor focus, memory issues, mood disorders, and developmental problems
